Typical Applications Multicolumn Selection

Advantages: Increase productivity

Higher instrument up-time

Quickly change between up to four different stationary phases for different applications, or use identical stationary phases in columns with different dimensions for either faster run-times (short columns) or higher resolution (long columns) or for loading studies with different internal diameters.

Installing the Valve Heads The valve drives are factory-installed in the Thermostatted Column Compartments, in the 1290 Infinity Flexible Cube, and in the 1290 Infinity Universal Valve Drive. The valve heads are interchangeable and can be easily mounted.

At the first installation, the transportation lock (TCC only) and the dummy valve have to be removed, see Removing the transportation lock and the valve dummy (only if used with TCC) on page 9. The valve heads can be installed by mounting the valve heads onto the valve drives and fastening the nut manually (do not use any tools).

Be sure that the guide pin snaps into the groove of the valve drive thread.

NOTE TCC only:

The valves are mounted on pull-out rails to allow easy installation of capillaries. Push the valve gently into its housing until it snaps into the inner position, push it again and it slides out.

If all capillaries are installed, push the valve back into its housing, see section Installing the Valve Head and Connecting Capillaries in the TCC-Manual.

8

Removing the transportation lock and the valve dummy (only if used with TCC) The following procedure demonstrates the necessary steps for installing the valve head to the valve drive of a TCC.

For the installation of a valve head to a G1170A 1290 Infinity Valve Drive or G4227A 1290 Infinity Flexible Cube you can ignore the steps that describe the TCC features of the transportation lock and spring loaded valve drive.

1 When unscrewing the transportation lock (TCC only), push it back until the last screw is removed - the valve rail is spring-loaded

2 To remove the valve dummy, loosen the nut manually.

9

Installing the valve head and connecting capillaries (with the TCC as an example)

CAUTION The valve actuator contains sensitive optical parts, which need to be protected from dust and other pollutions. Pollution of these parts can impair the accurate selection of valve ports and therefore bias measurement results.

Always install a valve head for operation and storage. For protecting the actuator, a dummy valve head can be used instead of a functional valve. Do not touch parts inside the actuator.

CAUTION Column Damage or Bias Measurement Results Switching the valve to a wrong position can damage the column or bias measurement results.

Fit the lobe to the groove to make sure the valve is switched to the correct position.

CAUTION Valve Damage Using a low pressure valve on the high pressure side can damage the valve.

When using multiple column compartments as part of a method development solution, make sure that the high pressure valve head is connected to the autosampler and the low pressure valve head is connected to the detector.

NOTE For information about the compatibility mode of 800 bar valve heads see Information on RFID Tag Technical Note (01200-90134).

10

NOTE The tag reader reads the valve head properties from the valve head RFID tag during the initialization of the module. The valve properties will not be updated if the valve head is replaced while the module is on. Selection of valve port positions can fail if the instrument does not know the properties of the installed valve.

NOTE The Agilent 1290 Infinity Valve Drive recognizes the valve correctly, only if the valve drive was powered off for at least 10 s.

NOTE For a correct installation of the valve head, the outside pin (red) must completely fit into the outside groove on the valve drives shaft (red). A correct installation is only possible if the two pins (green and blue) on the valve head fit into their corresponding grooves on the valve drives actuator axis. Their match depends on the diameter of the pin and groove.

NOTE For firmware requirements see Information on RFID Tag Technical Note (01200-90134) which is included to each valve head.

11

The following procedure demonstrates the necessary steps for installing the valve head to the valve drive of a TCC. For the installation of a valve head to a 1290 Infinity Valve Drive or 1290 Infinity Flexible Cube, you can ignore the steps that describe the TCC features of the spring loaded valve drive.

1 Insert the valve head into the valve shaft.

OR

If the outside pin does not fit into the outside groove, you have to turn the valve head until you feel that the two pins snap into the grooves. Now you should feel additional resistance from the valve drive while continue turning the valve head until the pin fits into the groove.

12

2 When the outer pin is locked into the groove, manually screw the nut onto the valve head.

NOTE Fasten the nut manually. Do not use any tools.

3 Install all required capillary connections to the valve.

13

4 Push the valve head until it snaps in and stays in the rear position. (TCC only)

5 Power on or power-cycle your module, so the valve head gets recognized during module initialization.

NOTE Power Off the Infinity valve drive for at least 10 s.

14

Connecting Valves, Heat Exchanger and Columns Installation of the Low Dispersion Heat Exchanger Double Assemblies The device is typically mounted into the center location of either the left or the right heater element where it can support two columns.

The additional heater can be arranged in the G1316C in various locations depending on the application needs. Some examples are shown in Figure 3 on page 15.

Figure 3 Arrangements of Heating and Cooling Devices (G1316C)

NOTE If the additional heating and cooling devices are used as shown in Figure 3 on page 15 (top), the column identification system cannot be used. If the column identification system is required, fix the heating and cooling devices in the upper or lower locations or fix them right/left of the current location.

NOTE The maximum flow rate to be used with the Low Dispersion Heat Exchangers is 2.5 mL/min at 100 C and 20 C ambient.
